APPARATUS FOR PASTEURIZING AND COQLIHG. BEER.

Application filed July 8, 1908. Serial N To all whom it may concern:

lie it known that I, lViLLiAM \i'nnznii, a. citizen of the UnitedStates, residing at Appleton, in the county of Outagamie and State oflYisconsin, have invented new and useful Improvements in Apparatus forPas teurizing and Cooling Beer of which the following is aspecification.

This invention relates to an apparatus tor pasteurizing and cooling beerin bottles and aims to provide an apparatus of such class with means ina manner as hereinafter set forth whereby the beer in the bottles willbe subjected to a circulating medium of progressively inci asingtemperature until the desired temperature is reached then maintainingsuch circulating irediuin at such tennoerature a predeterniinet periodof time until the pasteurization is completed, after which thepasteurized beer is cooled by subjecting it to a circulating medium ofgradually decreasing temperature until the cooling step is completed.

Further objects of the invention are to provide an apparatus of theclass referred which shall be simple in its constructiim, strong,durable, efficient in its use, conveniently operated, readily set up,and comparatively inexpensive to manufacture.

Vith the foregoing and other objects in view the invention consists ofthe novel construction, combination and arran ement of parts hereinaftermore specifically described and illustrated in the accompanying drawingswherein is shown the preferred embodiment of the invention. but it is tobe understood that changes, variations and modifications can be resortedto which come within the scope of the claims hereunto appended.

In the drawings z l igure l is a longitudinal sectional view ot apastenrizing apparatus in accordance with this invention, the sectionbeing taken on the line 1-1 of Fig. 3. Fig. 2 is an end view inelevation. Fig. 3 is a plan broken away. Fig. l is a transverse sectionon the line -l--l of 2'3. 5 is a sectional plan on the line ol? 1, andFigs. 6 and T are respectively a elevation and an end view partly insection of a convenient form of crate or basket for supporting thebottles containing the beer within the apparatus.

Specification of Letters Eateut.

Referring to the drawings by reference charl acters, 1 denotes a tankhaving a hinged top 2 and in which is adapted to be mounted r basketcarrying bottles 4 containing the liquid to he pasteurized. hepastenrizing medium is water having the temperature thereof progressvely increasing while the cooling medium is water having the temperaturethereof gradually decreasing. The ref erence character I; denotes awater teed pipe coinnninicating with awater supply and c J a. U11- m x Iprovided who a CtlL-Oii b. rho reterence character 7 denotes a steamteed pipe coinnninicating with he steam supply and formed with acuto1ll' Arranged within the tank 1 at the to thereof is a plurality ofcombined watesupply and draw oft pipes 5), 10 each of which is formedwith a series of orifices it for supplying or withdrawing the wate fromthe top of the tank. The pipe 9 at each end is bent in a vertical manneras at 12 and the upturned ends 12 ot' the said pipe 9 are connected tothe transversely extending branch pipes 13 by the T-couplings l t. Thebranch pipes 1 3 at one end each depend downwardly as at 17) and thesaid depending ends 15 terminate in a pipe 10. The other end ol each ofthe pipes 13 is bent do wardly as at 16 and terminates in alongitudinally extending conduct ing pipe 17. The latter is connected tothe straps 18 which are fixed to the cover and constitutes the pivot forthe cover Stops or collars 19 are carried by the cover 2 in which thepipe 1'? pivots and the pipe 1? is swivelly connected as at 20- to abranch pipe 21 and by such an arrangement the raising and lowering ofthe cove 2 can be had when occasion so requires. 'lhe depending portions15 ot' the pipe l3 extend through the cover 2 and the upwardly extendingportions of the pipe 9 project through the cover 2. .lly such anarrangement when the cover is raised the pipes i0 and 13 are. carriedtherewith and a like action is had when the cover 2 is lowered. Thebranch pipe 21 communicates with a coupling pit e 22. ihe latter opensat one end into a coupling 23 which communicates with the water teedpipe 5 and at its other end opens into a coupling which connnunicafeswith a vertically xtending conducting pipe The )ioe embodies avorticallv extending nor- 1 .L I l tion and an itplki and a lowerangularly disposed portion. the upper portion ext-ending at an anglewith respect to the lower portion and said lower portion is of greaterlength than said upper portion and is pro vided with the cut-otls it;Intermediate the lower portion of the pipe a suction loo pipe 27communicates therewith and with a pump 28 driven by a pulley 29connected with the prime mover, not shown.

The outlet pipe for the pump 28 is -indicated by the reference character30 which communicates with abranch pipe 31 projecting from the coupling23 and having a cutoft 34. A branch pipe 35 having a cut-off 36communicates at one end with the outlet pipe 30 and with a coupling 37in which opens the feed steam pipe. A branch pipe 38 opens at one endinto the coupling 37 and at its upper end in the coupling 24. Theconducting pipe 25 which commimicates with the coupling 24 has its lowerend as at 39 bent in an angular manner and opens into a transverselyextending branch pipe 40 which terminates at each end in alongitudinally extending combined water supply anddraw-oif pipe. Thesepipes are indicated by the reference characters 41 and 42 and eachprovided with a series of orifices 43. Each of the pipes 41, 42terminates at its inner end in a transversely extending branch pipe.These branch pipes are indicated by the reference characters 44, 45,each of which opens into a longitudinally extending combined watersupply and drawoff pipe. These latter pipes are indicated by thereference characters 45 46 and are positioned in parallelism withrespect to the pipes 41, 42. The pipes 45, 46 at their outer ends arebent outwardly as at 47 and each of said bent ends 47 opens into abranch pipe 48 and these pipes 48 communicate with the conducting pipe25.

The pipes 41, 42 and 45', 46 are arranged in close proximity to thebottom 49 of the tank 1, and terminate at one end at a point removedfrom the side wall 50 of the tank 1 and at their other ends extendthrough the side wall 51 of the tank 1. The branch pipes 40, 48 arearranged exteriorly of the wall 51 and the same is true of theconducting pipe 25.

Surrounding the tank 1 exteriorly thereof is a conducting pipe 52 forthe over-flow and which communicates with the interior of the tank 1through the medium of a series of outlet pipes 53, these latterextending and opening into the tank 1 at a point below the centerthereof. The pipe 52 is common to all the outlet pipes 53 and opens intoa stand pipe formed of a stationary section 54 and a shiftable section55. The latter has communicating with the top thereof a discharge pipe56. The section 54 of the stand pipe is provided with a acking box 57 inwhich is arranged a glanc 58. Through the latter extends the section 55.The section is vertically adjusted through the medium of the lever 59pivoted to the wall 50 as at 60 provided with a handle 61 and connectedto the section 55 by the link 62. By providing an adjustable stand pipeit is evident that the depth of the body of water within the tank 1 canbe regulated. The stand pipe and its connections constitute what may betermed a water gage. V

The crates, racks or receptacles 3 are mounted upon the supports 63 andprovided with a bail 64 whereby the crate, rack or receptacle can beremoved and positioned in the tank 1 when occasion so requires. The pump28 is mounted upon a laterally extending bracket 65 which projects fromand is secured to the wall 51.

The pipes 9, 10 are positioned the desired distance apart so that thewater will be drawn from or discharged at different points at the top ofthe tank and the same is true of the pipes 41, 42. This arrangement ofperforated pipes facilitates the circulation of the pasteurizing mediumwhich by way of example is heated water and the cooling medium which byway of example is water gradually decreasing in temperature.

The operation of the apparatus is as fol lows :It will be stated thatafter the crates or receptacles containing the bottles filled with beerare positioned in the tank, the tank is completely filled with water ofsuitable temperature through the medium of the pipes 5, 22, 17 and 13and 9 and 10. During the filling of the tank with water, the cut-offs 27and 34 are closed. It will be assumed that the tank has been filled withwater, the cut-ofi (3 is then closed, the cut-off 27 opened, the cut-off34 remaining closed, the cut-off 36 opened and the cut-off 8 opened,whereby steam is admitted to the conducting pipe The pump 28 is operatedand by such action water is drawn from the top of the body of waterwithin the tank 1. The water passes from the tank 1 out through thepipes 9, 10, 13, 17, 21, 27 through the pump, pipes 30, 35, into thebranch pipe 38. At this point the steam entering the branch 38 willincrease the temperature of the water. heated water is conducted throughthe pipe 25 and discharged into the bottom of the tank through themedium of the pipes 41, 42, and the connections between said pipes andthe conducting pipe 25. This forced mechanical circulation, 2'. 6.drawing the water from the top and rentering it into the tank at thebottom will cause the water to have the temperature progressivelyincreased, owing to the supply of steam to the branch 38. After thewater has been heated to a desired temperature, it is maintained at sucha temperature for a predetermined period to complete the pasteurizationof the beer and when it has been determined that the pasteurization hasbeen completed, or at any time as may be desired the steam supply isshut off by closing the cut-0E 8. The cutofls 27 and 36 are also closedand the cut-ofis 26, 34 and 6 opened, the operation of the pump isreversed and the water is drawn The nae-e27 and rentered rater passingand the confrom the ho -tom oi the tank into the tank at the top, theout through the pipes ii, e2,

nections therebetween and the coi'iducting pipe From there the waterpasses through. the lower portion of t i pi )e and nto t ne pump, thenup through t re pipe into the bran the cold.

The overflow oi the cooling medium and heating medium is provided for bythe manner in which the outlet pipes 53 couanunicatc with the inteior ofthe tank and rise with the common conducting pipe the latter openinginto the stand pipe. The level of the water within the tank can beregulated owing to the adjustability of the stand pipe, as will beeyident, or in other words the adjustabiliiiy of the stand pipeprovide-i for regulation oi the discharge from the tank.

By setting up the apparatus in the man nor as hereinbetore described, itwill be evident that the suction of the pump through the perforatedpipes taking the water from all parts of the tank and after heating itforcing it into the bottom embodies several distinct principles, first,circulation by suetion at the top, thereby also lifting the enteringheated water from the bottom, second, the natural circulation caused bythe rising of the heated water, and third the tion by forcing the heatedi'ate tank by the pump which is aide "l circuit into the V d by therising of the heated rater and i re lifting oi the heated water bysuction. In retoronce to the cooling, it will be said that the hot wateris drawn from all parts oi the bottom of the tank and forced into thetop of the tank through the pcrtoi'ated pipes, the heated water prior toits entering the two of the tank being mixed with cold ater and as thecold water is heavier than the hot water, it naturally grayitates to thebottom. By the arrangement of perto ated pipes, each is supplied fromboth ends, giving an equal distribution of water throughout the tank andalso drawing from all parts of the tank. in causing the over-flow waterto waste at the sides of the tank at or near the center lines of thesides and ends, three distinct n eans of circulation during the coolingprocess are obtained, first, circulation caused by the naturalgravitation of the cold water to the bottom or the tank, second,circulation caused by wasting the over-flow water at the sides a id endswhich aids in the gravitation of the cold water to the bottom of thetank, and third, circulation caused by suction at the bottom of thetank, all of which ends to cause a rapid, uniform, thorough and completegradual cooling of the rater in all parts of the tank.

By setting up the apparatus in the manner as hereinbetore set forth auniform circulation of the water into which the botles containing theher are submerged is obtained, whereby the beer will be subjected touniform temperatures gradually increasing when pasteurizing andgradually decreasing when cooling, thereby giving each bottle containingbeer no matter where placed the sa no treatment.
